This manuscript presents a UWB filter with three notch bands for WiMAX, WLAN, and X-
Band Satellite Communication by introducing inverted E-and T-shape resonators shorted at …

This paper presents an ultra-wideband bandpass filter (UWB-BPF) with a notch band and a
wide upper stopband. Two pairs of half-wavelength high-impedance line resonators tightly …

In this paper, a series of novel reconfigurable-bandwidth notched-wideband bandpass filters
(NWB BPFs) with controllable notch bands are proposed. The proposed filters start from a …

In this paper, a stub-loaded square ring resonator (SLSRR) is analyzed and applied to
design a very simple and compact wideband bandpass filter structure. Resonant modes …

This article presents a simple method to design an ultra-wideband (UWB) bandpass filter
(BPF) with a notched band. The structure of the filter is simple and is composed of a single …

A broadband balanced-to-single-ended (BTSE) four-way power divider (PD) with out-of-
phase is designed in this letter. The proposed four-way PD composed of three-series T …

In this paper, we develop a bandpass filter using a stub-loaded stepped impedance
resonator (SLSIR) and calculate the even and odd resonant modes of this type of resonator …

In this paper, we present a simple method to design a miniaturized wideband bandpass filter
with suppression of the third harmonic, using only two quarter-wavelength stepped …

A simple chiral medium is used to enhance the response of a conventional microstrip
coupled line bandpass filter (BPF). The approach is applicable to both narrowband and …

Stepped impedance resonator (SIR) and its derivative resonators are widely used in the
design of microwave filters. However, many spurious modes will be introduced into the …
